Question about WIFI calling development - AT&T Samsung Galaxy S7 Edge Questions & Answers

since we have root for our phones can someone tell me what to change to have wifi calling on all the time not just when we have low signal?

Just for those who might not know: even without root, you can always force WiFi calling by (1) turning on Airplane Mode (which turns off WiFi if it's on); (2) turning WiFi back on, leaving Airplane Mode on (you can also re-enable BT and NFC). Then you've got WiFi calling.
But it would be more convenient to have WiFi calling stay turned on without needing Airplane Mode. I don't know if/how rooting lets you do that.

How to switch off GSM/3G Radio?

Very interested! Coz I have poor signal reception inside my home (signal is worse than -100Dbm and sometimes vanishes at all) and basically I don't need cell-connection sometimes. So, how should I act to temporally disable cell-module? Airplane mode doesn't suit me coz I need working Wi-Fi connection, but Airplane mode turns everything off. All I need is only Wi-Fi enabled to preserve battery power. Help me please.
However I found solution myself. Look for OneClick Widget on the Market. It allows to keep WiFi on even when changing to Airplane mode, also it allows to toggle WiFi when in Airplane mode.

[Q] How do you turn off 3G without turning off GPS?

Does anyone know how to turn off the 3G radio without turning off the GPS?
I know the airplane mode trick will turn off 3G but that also turns off GPS, which some Google apps need.
I hope Google gives us dedicated radio toggles in 3.1.
Try unchecking 'Data enabled' in mobile network settings

That is the correct way to do it.
Airplane mode really should be used when you want ALL of the wireless turned off, including wifi. It's strange that it lets you turn it back on while in airplane mode. I guess it makes sense for those planes that now have wifi.

Also how i use my phone overseas without having to worry about a big ass bill.
Are you sure GPS is off in Airplane Mode? I run in A-M too when I'm on WiFi, and I've definately seen the "GPS on" indicator come up when doing something that needs my location.
But to be sure, I downloaded "GPS Test" from the market, turned on Airplane Mode after getting it, and GPS test was able to see some 6 satellites (inside- we have some really nice hardware!).
I don't think GPS is off when in A-M.

Well, it actually does kill-switch everything when enabled- which is what it's supposed to do, but it's a good thing that it allows selective re-enabling of BT and WiFi.
Besides, GPS is a reciever (unlike BT/WiFi which also Xmit), but while I'm aware of the heterodyne issue, that leakage is FAR smaller, and the only way to fix that is to turn off the device altogether.

Disable cell signal

Anyone know if I can disable the cell signal automatically on the unrooted nexus 6P?
I know I can pop it in airplane mode and then turn back on bluetooth & wifi but I want to automate this process so that when I'm at work it will toggle the cell radio off.
Any ideas?
Ok, so I setup tasker to turn on Wifi and Bluetooth when I put the phone in airplane mode. It's not ideal but it's a start.
If anyone's got a better idea, please let me know
I am assuming I can't turn off just the cell without root.
Can't you use NFC tags for tasks like this?
I can't find anything saying it would work airplane mode or turning the cell off though.

Any way to prioritize WiFi calling whenever you are connected?

Much like the iPhone, WiFi calling only works when your cell signal is low. Is there any way to force it to always use WiFi calling regardless of cell signal? The only way I found is to put the phone into Airplane Mode, and turn wifi back on. I would rather not have to do that because I have already forgotten to turn the cell back on when I leave my house lol.
Thanks.
Without root, an automated way to do this (like with Tasker or Macrodroid) doesn't seem possible because 3rd party apps cannot change or set Airplane mode.
However, you could set up an automated task to remind you when the detection status of any chosen wifi SSIDS changes, so you wouldn't forget to change your settings when entering or leaving a specific wifi area.

Wifi networks don't show up in airplane mode but do when airplane mode off

this has been very vexing mainly because I don't know how to craft the google-fu to get beyond "no wifi in air plane mode".
Basically, when you turn on airplane mode it disables wifi. You can then enable it an all is good. However, for me it appears that when you disconnect from a wifi network in airplane mode the wifi network can no longer be connected. Once you turn airplane mode the wifi network comes back up but if you enable it the wifi network is gone. Other wifi networks are still there in both modes but just not the one you forgot.
Using wifi analyzer the wifi network is still being detected by the phone but the phone won't connect.
Any thoughts on how to solve this one?
For future readers it appears that if you run into this issue you can turn off airplane mode connect and then turn airplane mode on again and it will work. Sometimes. This is my solution until I can figure out what the heck is actually happening.
